If the environment reaches – 40 °C, Palazzo can provide a special version of this cable (differentiated from the standard one by the
“-K” add to the code name), which is constructed with a special rubber compound that can face this condition. For temperature down
to – 40 °C we suggest to use the Panzerflex-K. To allow this cable operating at – 40°C we use an outer-sheath compound that is less
resistant to abrasion and tear so please contact our sales department for more information regarding application.

*Tabulated values are valid up to three loaded conductors with or without earth.
Derating factor shall be used for multicore cables depending on loaded conductors. See page 45.
The Tensile Load on control cables is calculated considering the limit of 15N/mm2
instead of the standard 20N/mm2
. This is due to the construction of these multi-core
cables. For higher Tensile Load please consider to use our VS type as it is provided of a central Kevlar®
strainer that allows much higher tensile loads.

*Tabulated values are valid up to three loaded conductors with or without earth.
Derating factor shall be used for multicore cables depending on loaded conductors. See page 45.
The Tensile Load on control cables is calculated considering the limit of 15N/mm2 instead of the standard 20N/mm2. This is due to the construction of these multi-core
cables. For higher Tensile Load please consider to use our VS type as it is provided of a central Kevlar® strainer that allows much higher tensile loads.

Foreword
In the following pages, you will find some major tech-
nical information organized in handling/installation
and Electrical.
Our goal is provide you with all the easy, most com-
mon information in order to deal correctly with all our
cables (from the project to the final handling).
Obviously we prefer if you would contact us for any
specific, as our sales department and our technicians
can act together in order to help you best in this way.
Cable guides
After considering the correct reeling system, the cable guides became the next step to be looked at properly.
Some misuse of the handling of these guides lead to some major reeling system problems. Amongst the various guide
types the best are the radius types as they provide generous bending radii with minimum cable deflection. Our last
mandatory recommendation is to keep the guide exactly aligned with the payout plane of the cable: every misalignment
can lead to an increase of torsion on the cable itself.
Change of direction
At the designing stage of a cable winding system, please keep an eye on leaving enough distance between any changes
of direction. The best and recommended distance should be at least 20 times the cable OD (even longer for high speed
systems). This behavior will leave the cable to regain its starting shape before suffering another bending.
The above table gives the recommended minimum
bending radii for different cable uses. Observance of these
recommendations and a precise calculation of the bending
radius is important as one of the most important factors of
reliability. Increase on minimum bending radius has a more
than proportional effect on the life of a cable because it causes
stretching and internal torsions due to increased mechanical
stresses in the conductors. As the frequency of movements is
important, a tighter bending radius may be considered where
movement is slow and/or occasional.
Care must also be taken and limits imposed on design where
pulleys or guide rollers (same radii as for collection reels) are
present or where there is a flexion and torsional stress due to
reel being parallel to the line of travel of the machine.
A one way guide often appears even on two directions payout as it
seems the most economic solution.
However a considerable increase in cable life is obtained if a
two way guide is used: in fact the net torsional and “massaging”
effects imparted by the guide to the cables are balanced using a
symmetrical two way one. This problem doesn’t occur if the reeling
system is end fed. In this case the one-directional guide is in contact
with the cable regardless of the direction of travel of the machine.
It is highly recommended that cable guiding systems include both
under and over tension protection systems. Even a short exposure
to over tension caused by mechanical failure or accidents
can render a cable inoperable due to permanent conductor
deformation or breakage. Conversely, under tension protection is
desirable to ensure that cable cannot free spool from the reel and
sustain damage. This protection is particularly important for high
mounted cable reels. All over tension protection devices should
be set to the maximum continuous safe working tension defined
for each cable section.
Comparing them with the previously described guide types, some
difficulties are clear. The sheaves’ weight increases inertia, so more
torque is needed to compensate it giving a final increase on cable
tension so reducing its life. Another disadvantage to be considered
from using a sheaved guide is the detrimental effect onto the cable
outer sheath that is directly in contact with the sheave circumference.
This contact area should increase if a hollow internal sheave shape is
used. This becomes a particularly significant condition that will lead
to a considerable reducing of the cable life and this is why we suggest
to use a correct sheave profile as shown in the below image.

Over and under tension protection
Sheaves
A part from this, the two-way guide
or the multi roller systems, this is the
preferred one.
Multi roller or two-way guide should be
designed to continue the arc beyond
the angle of deflection. In this way
the minimum bending radii is always
maintained.
Incorrect sheaved profile
Torsion is induced on the cable due to
rolling effect leading to a reducing in
cable life.
Correct sheaved profile
This design minimizes torsion applied on
the cable.
As a general note, you have to absolutely
avoid any abrupt changes of the bending
radius (often this is due to a not enough
long angle of deflection of the roller
guide arc).
These changes lead to a punctual
overpressure that results into a cable
breakage.

Anchoring systems
Correct cable anchoring is important in establishing reliableoperation of a cable handling system. According to the cable
handling system typology, different methods may be used, but all of them share the same basic intent: spread the tensile
forces over a sufficient large cable sheath area in order to avoid damage or failures at the anchoring point.
The most common mobile anchor points are performed using the ordinary terminals or “cable grips”. In these cases it is
recommended that the tensile load would be distributed over an end length of the cable equal to 20/25 times its OD, and
that a slack loop of cable will be left before entry into the terminal box in order to allow the operating movements. When
an underground centre point attachment is installed, the vertical distance between the entry bell and the crane’s payout
guide should not be less than 15 times the cable OD or 1m, whichever is larger. At least 21/2
cable turns should be wound
around the fixed stress relief drum to ensure sufficient contact area for an adequate stress relief. Dynamic tensile stress
on the cable can lead to premature failure, especially in high travel speed applications. In order to minimize this, several
solutions are at hand, as the most important - according to our experience - is a travel speed reduction device. This system
can be incorporated with most reel drive designs. It reduces the travel speed before reaching the centre point, and then
re-accelerates once the centre point has been passed and the reel direction of rotation has been reversed.
Handling and installation
For optimum long life service, laying operations must be carried out by expert personnel. In addition to the normal
measures to be observed when laying cables, the following recommendations, specific to the operating conditions for
mobile cables, must be strictly adhered to. It’s always a good practice to test the installation a few times as soon as the
cable as been laid to check operation and immediately correct any eventual defects or faults.
Handling of cable
Storing and handling of cables on the original drums
is recommended in order to prevent the formation of
defects caused by loose coils. If possible avoid, or at least
minimize, to roll the drums on its flanges: on the other
hand, use a fork-lifter or crane to move the reel. If you
cannot avoid to roll the drum, do it against the coiling
direction not following. This small suggestion will keep the
cable coiled tight to the reel and will prevent any torsion
or abrupt tensions given by loose coil action. A further
recommendation regards storage.
Spare cables have to remain on their original drums (it
prevents coils slumping); moreover - even you consider
either a short or long cable storage - the cables’ drums
must be kept in a cool, dry and shaded location and the
cable’s ends must be sealed (as done on first delivery) in
order to prevent the entrance of moisture and dirt.
Cable installation
Generally, when a cable is installed onto a force guidance
system as the reeler, festoons, gravity-fed (spreader) basket,
the transport drum should be jacked up above ground level.
The preferred method to operate a cable installation on
site consist first of all in jacking up the original drum then
unwinding the cable all along the entire machine’s travel
route. You can use conventional cable pulling equipment and
rollers to perform this action. Sometimes these procedures
cannot be used due to the environment or site conditions so
you can act transferring it directly from the drum to the reel.
It is also a recommended method when reel location and/or
cable runaway are not accessible. In this case you must avoid
to introduce “S” bending between the drum and the reel.
Whenever possible the cable should be transferred directly
without passing through or over any rollers or change of
directions. The directly transferring from the transport drum
to the final reel must be done slowly and with a minimum
tension: this behavior would avoid any torsional influence
during cable installation.
The following pictures show how to proceed generally when
unreeling the cable from the original drum and transferring it
directly to the final operating system.
Cable reels
Correct cable anchoring is important in establishing reliableoperation of a cable handling system. According to the cable
Cable life and performances is tightly connected to the reeling design. A well designed reeling system, combined with the
correct choice of the cables, secures optimal performances of the whole system and also can assure a long lasting operative
cables, increasing their life and reliability. Today’s market uses a wide range of cable reels that can be sum marized in three
main types: you can find herewith a brief description of each one with some hints about their advantages and disadvantages.
Anchoring system for center crossover
1. Cable support
2. Entry bell
3. Stress bearing drum
4. Cable wound twice (21/2
) around stress bearing drum
5. Supply cable
6. Cable termination box
7. Clamp
It is one of the most diffused. It has a simple guide route that
gives - as a result - an extension to the cable’s own life in
comparison to the other types.
Moreover on these cable reels (due to the improved heat
dissipation), the conductor size for the power cables are
generally smaller in comparison to the other kind of reels. The
cable diameter and length are main factors to be considered for
the application on mono-spiral reels: the good balance between
reel’s inner and outer diameter, will be critical for determining
and controlling the cable tension.
It is the simplest type amongst the existing cable reels: it operates
without guides so the random layering can create severe operational
difficulties such as slippage of coils, abrupt tensile forces, torsion,
abrasions and abnormal build-ups. For these main reasons this
application can support only small cable diameters and short runs:
250m maximum run, and a weight approx. < 4 kg/m.
It is indicated for large cable diameters and long lengths. The main
advantage on using this type of reel is its ability to carry large amount of
cable (even with large diameters) at a constant reeling tension and for
long distances. On the other hand, normally due to the reel location, is
also difficult to reduce the number of guides and changes of direction
on this type of installation.

If, during the above procedure, the cable has become twisted, we strongly recommend to eliminate it. Normally two methods are
foreseen to perform this action.
Wave Motion
Insert a cylinder roller (the diameter of which should be between 15/20 cm) underneath the cable near to the twisting. At this point
two people should walk handling the roller and pushing the “wave” towards the end of the cable. You can perform this action until the
detected twist is removed.
Spiral Method
This could be carried out by one person only and will reach the same effect described above. Allow enough cable from the fixed end
of the cable (better from the drum jacked on) in order to obtain a spiral. This should be a right side or a left side one according to the
direction of the detected twist.
The spiral will be rolled to the free end of the cable in order to remove any twisting. This action must be performed again for each
founded twisting. Then re-anchor the cable to start operation. If during the first test-running of the equipment you still find a slight or
residual twisting, lead the machine to the end run then un-anchor the cable (eventually cutting 25/50cm of cable) and eliminate the
torsion. After this, re-anchor the cable and have a final check. Please keep in mind that a cable correctly installed, if no torsions are
introduced by guides or unnatural bending, it cannot twist (for an evident physical law).
For this reason we suggest that during the final check, you draw some marks on the cable than let the machine run in order to can
easily determinate if the cable starts to twist. If yes the whole system has to be stopped in order to find and eliminate the external
cause of the torsion.
Note: the cable marking can show a natural slight spiral effect (more evident on long cable lengths), but this aspect is totally not related to any kind of twisting problem.
PANZERFLEX crane cables are manufactured with right hand lay-up of the conductors (power and control cable) and therefore when
winding onto multi-spiral reels, the first turn must be with the cable against the right flange of the reel.
This will have the effect of exploiting the natural tendency of the cable under traction to move to the right, keeping subsequent turns close together.
To assist the movement of the cable over guide rollers, sheaves,
etc. a dry lubricant or a silicone based grease may be used as
these types of lubricants avoid dust and dirt from adhering to the
lubricated surface.

Cables installation for vertical application
(BASKETHEAVYFLEX, PANZERFLEX-VS, PANZERLITE)
Cables installation on a spreader or other kind of vertical application, needs to follow some major attention, mainly due to the
specific kind of application.
Main recommendations given in the previous paragraphs (wound the cable from the original drum; avoid to subject the cable to
unnecessary loops, torsion or twisting; eliminate any eventual torsion, etc.) must be followed also for these cables. Moreover the
installation has to go after all the topics given herewith.
When necessary, the bottom of these cables would be fixed by a suitable grip. The sheath
coverage is the same of the anchoring system (20/25 OD of the cable). The distance from the end
of anchoring device to the end of the machine travel should be at least 40 x cable OD. If frequent
dynamic stresses near the anchor point are anticipated a spring may be used.
Even if the Basketheavyflex cable has been especially designed for this type of
application, the correct design of the basket is important not only as far as cable life
is concerned, but also to avoid operating malfunction. High stress applications will be
typically involve long vertical lengths, high speed combined ascent and descent with
movement and, often, the presence of strong winds. In these cases care must be taken
to ensure that coiling diameter is not less than 1.5 m. A centrally guide cone centrally
placed into the basket is recommended for even coiling the cable correctly.The shape
of the basket and of the opening are also important operating factors: with high lift
and high speed a height of at least 2 m and a conical opening are recommended.
The best anchoring is achieved with a stress relief drum as shown on the below picture. The open ended construction facilitates
installation and replacement while affording better stress relieve and sheath protection than cable grips. In this case at least 21/2
cable turns should be wound around the drum. The table “Bending radii” show the minimum bending radii of stress relief.
If, on the other hand, the anchoring would be made with a grip, a recommended length of coverage over the cable is 20/25 times
the cable OD. This will aid in spreading the dynamic stresses over a sufficient sheath surface area to inhibit cable damage.

Scope of the information given herewith is to assure the PALAZZO PRYSMIAN’s deep
commitment to giving the customer the best support for a perfect use of our products.
Life and performance of our PANZERFLEX, depend directly on all the recommendations
and figures stated in this technical section.
Furthermore we would like to underline that the main topics that must be regularly
and carefully checked are:
➤ the perfect alignment of all equipments such as: lyres,reels, sheaves, etc.
➤ all the protection devices in order to avoid over and under tensions.
➤ any twisting induced (and not released) during installation or test-run activities.
The misuse of even one the above instructions will surely lead topremature cable
failures.
ELECTRICAL PARAMETERS
Electrical parameters
For the rated,operating and test voltages of cables, the definitions given in DIN VDE 0298, Part3, apply. Some of these are
mentioned in table 2.
AC - alternating current
DC - direct current
The rated voltage of an insulated electric cable is the voltage which is used as the basis for the design and the testing of the cable
with regard to its electrical characteristics. The rated voltage is expressed by the two values of power frequency voltage Uo
/U in V.
➤ Uo
rms value between one conductor and “earth“
➤ U rms value between two conductors of a multi-core cable or of a system of single-core cables
In a system with AC voltage, the rated voltage of a cable must be at least equal to the rated voltage of the system for which it is
used. This requirement applies both to the value Uo
and the value U.
In a system with DC voltage, its rated voltage must not be more than 1.5 times the value of the rated voltage of the cable.
The values for current carrying capacity and various correction factors given in the below table are the same as those dened by
standard VDE 02 98 Part 4, 08-2003. Although the cables contained in this catalogue are insulated with ethylene propylene rubber
(EPR) for which the admissible operating temperature for continuous operation is 90 °C, the current carrying capacities given here
are for conductor temperature of 80 °C.
This is to conform to VDE standards and also as a precautionary measure to take into account greater difculties with heat dispersion
for this type of cable.
The values are for three core cable, with or without earth conductor, not wound and resting on the ground with ambient air
temperature of 30°C.
For installations where it is known that the life of the cable will be reduced as a result of high mechanical stress or wear in the
sheathing, then thermal ageing will be of less importance. In this cases a maximum operating temperature of 90 °C can be
considered and the capacities given in table from 3 to 6 can be increased by, approximately, 7%.
The operating voltage is the voltage applied between the conductors Electrical parameters ELECTRICAL and earth of a power
installation with respect to time and place with trouble-free operation.
Regarding the test voltage of flexible cables, the values given in the corresponding parts of DIN VDE 0250 apply.
➤	 l Cables with a rated voltage Uo
O /U up to 0.6/1 kV
	 These cables are suitable for use in three-phase AC, single-phase AC and DC installations, the maximum continuously
	 permissible operating voltage of which does not exceed the rated voltage of the cables by more than 10% for cables with a 	
	 rated voltage Uo
/U up to and including 450/750 V 20% for cables with a rated voltge Uo
/U = 0.6/1 kV.
➤	 Cables in DC installations
	 If the cables are used in DC installations, the continuously permissible DC operating voltage between the conductors must not
	 exceed 1.5 times the value of the permissible AC operating voltage. In single-phase earthed DC installations, this value should
	 be multiplied by a factor of 0.5.

Calculation of cable cross section
For the transmission of a given current under given operating conditions, the current carrying capacities for standard
conditions of continuous operation discussed herewith must be adopted and necessary corrected.
Downwards adjustment may be required using correction factors for conditions relating to:
➤ Ambient temperature
➤ Number of layers and turns on reels
➤ Number of conductors simultaneously under tension
It should not be forgotten that non continuous operation will mean better cable performance.
With the actual tendency to increase cable operating lengths it is wise to check voltage drop, not just for Low Voltages but
for Medium to High Voltages too. In some circumstances it may be necessary to check the resistance of the cable to short
circuit currents both from a thermal view point and electro-dynamically induced forces.

capacities for NON
continuous operation
In some cases electrical operation is not continuous or it
is only partially continuous. It may therefore be advisable
to check the values for current circulating and operating
times, to see whether the cross cection of the cable can be
reduced.
A typical example of intermittent operation with hoisting
equipment consists of repeated cycles where, for example,
an operating period of 10 minutes of full load is followed by
a longer period with no load.
These 10 minutes taken as a percentage of total duration
DT of the cycle provides provides a percentage load factor.
Load Factor FC % = (10 mi / DT) x 100
In this case the current carrying capacity as calculated using
table 3, can be increased using factors given in table 7.

Short circuit current
In accordance with VDE standards 0250 c.8/75 the admissible THERMAL limits for short circuit current in heavy duty mobile service
cables, must be calculated using the following reference values:
Initial = 80 °C (cable under full load)
Final short circuit temperature = 200 °C
The short circuit currents (thermal limit) given in the below table 8 have been calculated using these reference values and are valid
for a base time of 1 sec.
For other time periods, taking into account the protection characteristics of the apparatus, the value in the table must be divided
by the square root of the effective time (in seconds). For different initial and final temperatures (i.e. with 90 °C and 250 °C
admissible according to standards for EPR), the short circuit current (thermal limit) can be calculated using the following formula:
Icc (A) = kcc x cond. cross section (mm2)

Calculation
of voltage drop
Voltage drop should be checked not just for Low Voltage but
also for Medium Voltage connections where lengths are long.
The value is calculated by multiplying the factors K (mV/Am) of
the cable then by the length of the connection L (in km).
The formula to calculate the voltage drop is the following:
∆V= I x L x K (Volt)
where K=1,73 x (R cos + X sen )
I = (A) effective current capacity
L= (km) length of the connection
R= (Ohm/km) a.c. conductor resistance at 80 °C (see table 10 above)
X= (Ohm/km) cable reactance at 50 Hz (see table 10 above)
Values for electrical resistance R (80°C) and for reactance X
(calculated for round cables, 3 cores + 3 earth, but valid also
for at cables with sufcient approximation) are also given in the
above table 10.
It should be noted that for conductor temperatures of 90 °C the
resistance R must be multiplied by 1.03 while for a frequency of
60Hz the reactance X must be multiplied by 1.2 and the value
fKor (mV/Am) recalculated.
On the above table you can find our most common types of drum.
For each one also we provide internal and external dimensions,
weight, bulk space and volume. Please consider that a staved
drum increase its dimension D1 of 5mm in total.

Our goal is provide you with all the easy, most com- mon information in order to deal correctly with all our cables (from the project to the final handling). Obviously we prefer if you would contact us for any specific, as our sales department and our technicians can act together in order to help you best in this way. Cable guides After considering the correct reeling system, the cable guides became the next step to be looked at properly. Some misuse of the handling of these guides lead to some major reeling system problems. Amongst the various guide types the best are the radius types as they provide generous bending radii with minimum cable deflection. Our last mandatory recommendation is to keep the guide exactly aligned with the payout plane of the cable: every misalignment can lead to an increase of torsion on the cable itself. Change of direction At the designing stage of a cable winding system, please keep an eye on leaving enough distance between any changes of direction. The best and recommended distance should be at least 20 times the cable OD (even longer for high speed systems). This behavior will leave the cable to regain its starting shape before suffering another bending. The above table gives the recommended minimum bending radii for different cable uses. Observance of these recommendations and a precise calculation of the bending radius is important as one of the most important factors of reliability. Increase on minimum bending radius has a more than proportional effect on the life of a cable because it causes stretching and internal torsions due to increased mechanical stresses in the conductors. As the frequency of movements is important, a tighter bending radius may be considered where movement is slow and/or occasional. Care must also be taken and limits imposed on design where pulleys or guide rollers (same radii as for collection reels) are present or where there is a flexion and torsional stress due to reel being parallel to the line of travel of the machine. A one way guide often appears even on two directions payout as it seems the most economic solution. However a considerable increase in cable life is obtained if a two way guide is used: in fact the net torsional and “massaging” effects imparted by the guide to the cables are balanced using a symmetrical two way one. This problem doesn’t occur if the reeling system is end fed. In this case the one-directional guide is in contact with the cable regardless of the direction of travel of the machine. It is highly recommended that cable guiding systems include both under and over tension protection systems. Even a short exposure to over tension caused by mechanical failure or accidents can render a cable inoperable due to permanent conductor deformation or breakage. Conversely, under tension protection is desirable to ensure that cable cannot free spool from the reel and sustain damage. This protection is particularly important for high mounted cable reels. All over tension protection devices should be set to the maximum continuous safe working tension defined for each cable section. Comparing them with the previously described guide types, some difficulties are clear. The sheaves’ weight increases inertia, so more torque is needed to compensate it giving a final increase on cable tension so reducing its life. Another disadvantage to be considered from using a sheaved guide is the detrimental effect onto the cable outer sheath that is directly in contact with the sheave circumference. This contact area should increase if a hollow internal sheave shape is used. This becomes a particularly significant condition that will lead to a considerable reducing of the cable life and this is why we suggest to use a correct sheave profile as shown in the below image.

Multi roller or two-way guide should be designed to continue the arc beyond the angle of deflection. In this way the minimum bending radii is always maintained. Incorrect sheaved profile Torsion is induced on the cable due to rolling effect leading to a reducing in cable life. Correct sheaved profile This design minimizes torsion applied on the cable. As a general note, you have to absolutely avoid any abrupt changes of the bending radius (often this is due to a not enough long angle of deflection of the roller guide arc). These changes lead to a punctual overpressure that results into a cable breakage. Incorrect Correct
  • 25. 44 Panzerflex and Tunnelflex Cables www.utvcavi.com 45 Anchoring systems Correct cable anchoring is important in establishing reliableoperation of a cable handling system. According to the cable handling system typology, different methods may be used, but all of them share the same basic intent: spread the tensile forces over a sufficient large cable sheath area in order to avoid damage or failures at the anchoring point. The most common mobile anchor points are performed using the ordinary terminals or “cable grips”. In these cases it is recommended that the tensile load would be distributed over an end length of the cable equal to 20/25 times its OD, and that a slack loop of cable will be left before entry into the terminal box in order to allow the operating movements. When an underground centre point attachment is installed, the vertical distance between the entry bell and the crane’s payout guide should not be less than 15 times the cable OD or 1m, whichever is larger. At least 21/2 cable turns should be wound around the fixed stress relief drum to ensure sufficient contact area for an adequate stress relief. Dynamic tensile stress on the cable can lead to premature failure, especially in high travel speed applications. In order to minimize this, several solutions are at hand, as the most important - according to our experience - is a travel speed reduction device. This system can be incorporated with most reel drive designs. It reduces the travel speed before reaching the centre point, and then re-accelerates once the centre point has been passed and the reel direction of rotation has been reversed. Handling and installation For optimum long life service, laying operations must be carried out by expert personnel. In addition to the normal measures to be observed when laying cables, the following recommendations, specific to the operating conditions for mobile cables, must be strictly adhered to. It’s always a good practice to test the installation a few times as soon as the cable as been laid to check operation and immediately correct any eventual defects or faults. Handling of cable Storing and handling of cables on the original drums is recommended in order to prevent the formation of defects caused by loose coils. If possible avoid, or at least minimize, to roll the drums on its flanges: on the other hand, use a fork-lifter or crane to move the reel. If you cannot avoid to roll the drum, do it against the coiling direction not following. This small suggestion will keep the cable coiled tight to the reel and will prevent any torsion or abrupt tensions given by loose coil action. A further recommendation regards storage. Spare cables have to remain on their original drums (it prevents coils slumping); moreover - even you consider either a short or long cable storage - the cables’ drums must be kept in a cool, dry and shaded location and the cable’s ends must be sealed (as done on first delivery) in order to prevent the entrance of moisture and dirt. Cable installation Generally, when a cable is installed onto a force guidance system as the reeler, festoons, gravity-fed (spreader) basket, the transport drum should be jacked up above ground level. The preferred method to operate a cable installation on site consist first of all in jacking up the original drum then unwinding the cable all along the entire machine’s travel route. You can use conventional cable pulling equipment and rollers to perform this action. Sometimes these procedures cannot be used due to the environment or site conditions so you can act transferring it directly from the drum to the reel. It is also a recommended method when reel location and/or cable runaway are not accessible. In this case you must avoid to introduce “S” bending between the drum and the reel. Whenever possible the cable should be transferred directly without passing through or over any rollers or change of directions. The directly transferring from the transport drum to the final reel must be done slowly and with a minimum tension: this behavior would avoid any torsional influence during cable installation. The following pictures show how to proceed generally when unreeling the cable from the original drum and transferring it directly to the final operating system. Cable reels Correct cable anchoring is important in establishing reliableoperation of a cable handling system. According to the cable Cable life and performances is tightly connected to the reeling design. A well designed reeling system, combined with the correct choice of the cables, secures optimal performances of the whole system and also can assure a long lasting operative cables, increasing their life and reliability. Today’s market uses a wide range of cable reels that can be sum marized in three main types: you can find herewith a brief description of each one with some hints about their advantages and disadvantages. Anchoring system for center crossover 1. Cable support 2. Entry bell 3. Stress bearing drum 4. Cable wound twice (21/2 ) around stress bearing drum 5. Supply cable 6. Cable termination box 7. Clamp It is one of the most diffused. It has a simple guide route that gives - as a result - an extension to the cable’s own life in comparison to the other types. Moreover on these cable reels (due to the improved heat dissipation), the conductor size for the power cables are generally smaller in comparison to the other kind of reels. The cable diameter and length are main factors to be considered for the application on mono-spiral reels: the good balance between reel’s inner and outer diameter, will be critical for determining and controlling the cable tension. It is the simplest type amongst the existing cable reels: it operates without guides so the random layering can create severe operational difficulties such as slippage of coils, abrupt tensile forces, torsion, abrasions and abnormal build-ups. For these main reasons this application can support only small cable diameters and short runs: 250m maximum run, and a weight approx. < 4 kg/m. It is indicated for large cable diameters and long lengths. The main advantage on using this type of reel is its ability to carry large amount of cable (even with large diameters) at a constant reeling tension and for long distances. On the other hand, normally due to the reel location, is also difficult to reduce the number of guides and changes of direction on this type of installation.

  • 26. 46 Panzerflex and Tunnelflex Cables www.utvcavi.com 47 Incorrect Correct If, during the above procedure, the cable has become twisted, we strongly recommend to eliminate it. Normally two methods are foreseen to perform this action. Wave Motion Insert a cylinder roller (the diameter of which should be between 15/20 cm) underneath the cable near to the twisting. At this point two people should walk handling the roller and pushing the “wave” towards the end of the cable. You can perform this action until the detected twist is removed. Spiral Method This could be carried out by one person only and will reach the same effect described above. Allow enough cable from the fixed end of the cable (better from the drum jacked on) in order to obtain a spiral. This should be a right side or a left side one according to the direction of the detected twist. The spiral will be rolled to the free end of the cable in order to remove any twisting. This action must be performed again for each founded twisting. Then re-anchor the cable to start operation. If during the first test-running of the equipment you still find a slight or residual twisting, lead the machine to the end run then un-anchor the cable (eventually cutting 25/50cm of cable) and eliminate the torsion. After this, re-anchor the cable and have a final check. Please keep in mind that a cable correctly installed, if no torsions are introduced by guides or unnatural bending, it cannot twist (for an evident physical law). For this reason we suggest that during the final check, you draw some marks on the cable than let the machine run in order to can easily determinate if the cable starts to twist. If yes the whole system has to be stopped in order to find and eliminate the external cause of the torsion. Note: the cable marking can show a natural slight spiral effect (more evident on long cable lengths), but this aspect is totally not related to any kind of twisting problem. PANZERFLEX crane cables are manufactured with right hand lay-up of the conductors (power and control cable) and therefore when winding onto multi-spiral reels, the first turn must be with the cable against the right flange of the reel. This will have the effect of exploiting the natural tendency of the cable under traction to move to the right, keeping subsequent turns close together. To assist the movement of the cable over guide rollers, sheaves, etc. a dry lubricant or a silicone based grease may be used as these types of lubricants avoid dust and dirt from adhering to the lubricated surface. Twist removal Cable installation on multi-spire reels Incorrect Correct Connection point Single clamp Stress relief drum Typical cable anchoring method using a Kellems Grip® Good cable coiling Less controlled coiling Poor coiling control Typical cable anchoring method using a Kellems Grip® Fixed mounting Suggested Fixed mounting Cables installation for vertical application (BASKETHEAVYFLEX, PANZERFLEX-VS, PANZERLITE) Cables installation on a spreader or other kind of vertical application, needs to follow some major attention, mainly due to the specific kind of application. Main recommendations given in the previous paragraphs (wound the cable from the original drum; avoid to subject the cable to unnecessary loops, torsion or twisting; eliminate any eventual torsion, etc.) must be followed also for these cables. Moreover the installation has to go after all the topics given herewith. When necessary, the bottom of these cables would be fixed by a suitable grip. The sheath coverage is the same of the anchoring system (20/25 OD of the cable). The distance from the end of anchoring device to the end of the machine travel should be at least 40 x cable OD. If frequent dynamic stresses near the anchor point are anticipated a spring may be used. Even if the Basketheavyflex cable has been especially designed for this type of application, the correct design of the basket is important not only as far as cable life is concerned, but also to avoid operating malfunction. High stress applications will be typically involve long vertical lengths, high speed combined ascent and descent with movement and, often, the presence of strong winds. In these cases care must be taken to ensure that coiling diameter is not less than 1.5 m. A centrally guide cone centrally placed into the basket is recommended for even coiling the cable correctly.The shape of the basket and of the opening are also important operating factors: with high lift and high speed a height of at least 2 m and a conical opening are recommended. The best anchoring is achieved with a stress relief drum as shown on the below picture. The open ended construction facilitates installation and replacement while affording better stress relieve and sheath protection than cable grips. In this case at least 21/2 cable turns should be wound around the drum. The table “Bending radii” show the minimum bending radii of stress relief. If, on the other hand, the anchoring would be made with a grip, a recommended length of coverage over the cable is 20/25 times the cable OD. This will aid in spreading the dynamic stresses over a sufficient sheath surface area to inhibit cable damage.

Scope of the information given herewith is to assure the PALAZZO PRYSMIAN’s deep commitment to giving the customer the best support for a perfect use of our products. Life and performance of our PANZERFLEX, depend directly on all the recommendations and figures stated in this technical section. Furthermore we would like to underline that the main topics that must be regularly and carefully checked are: ➤ the perfect alignment of all equipments such as: lyres,reels, sheaves, etc. ➤ all the protection devices in order to avoid over and under tensions. ➤ any twisting induced (and not released) during installation or test-run activities. The misuse of even one the above instructions will surely lead topremature cable failures. ELECTRICAL PARAMETERS Electrical parameters For the rated,operating and test voltages of cables, the definitions given in DIN VDE 0298, Part3, apply. Some of these are mentioned in table 2. AC - alternating current DC - direct current The rated voltage of an insulated electric cable is the voltage which is used as the basis for the design and the testing of the cable with regard to its electrical characteristics. The rated voltage is expressed by the two values of power frequency voltage Uo /U in V. ➤ Uo rms value between one conductor and “earth“ ➤ U rms value between two conductors of a multi-core cable or of a system of single-core cables In a system with AC voltage, the rated voltage of a cable must be at least equal to the rated voltage of the system for which it is used. This requirement applies both to the value Uo and the value U. In a system with DC voltage, its rated voltage must not be more than 1.5 times the value of the rated voltage of the cable. The values for current carrying capacity and various correction factors given in the below table are the same as those dened by standard VDE 02 98 Part 4, 08-2003. Although the cables contained in this catalogue are insulated with ethylene propylene rubber (EPR) for which the admissible operating temperature for continuous operation is 90 °C, the current carrying capacities given here are for conductor temperature of 80 °C. This is to conform to VDE standards and also as a precautionary measure to take into account greater difculties with heat dispersion for this type of cable. The values are for three core cable, with or without earth conductor, not wound and resting on the ground with ambient air temperature of 30°C. For installations where it is known that the life of the cable will be reduced as a result of high mechanical stress or wear in the sheathing, then thermal ageing will be of less importance. In this cases a maximum operating temperature of 90 °C can be considered and the capacities given in table from 3 to 6 can be increased by, approximately, 7%. The operating voltage is the voltage applied between the conductors Electrical parameters ELECTRICAL and earth of a power installation with respect to time and place with trouble-free operation. Regarding the test voltage of flexible cables, the values given in the corresponding parts of DIN VDE 0250 apply. ➤ l Cables with a rated voltage Uo O /U up to 0.6/1 kV These cables are suitable for use in three-phase AC, single-phase AC and DC installations, the maximum continuously permissible operating voltage of which does not exceed the rated voltage of the cables by more than 10% for cables with a rated voltage Uo /U up to and including 450/750 V 20% for cables with a rated voltge Uo /U = 0.6/1 kV. ➤ Cables in DC installations If the cables are used in DC installations, the continuously permissible DC operating voltage between the conductors must not exceed 1.5 times the value of the permissible AC operating voltage. In single-phase earthed DC installations, this value should be multiplied by a factor of 0.5.

Downwards adjustment may be required using correction factors for conditions relating to: ➤ Ambient temperature ➤ Number of layers and turns on reels ➤ Number of conductors simultaneously under tension It should not be forgotten that non continuous operation will mean better cable performance. With the actual tendency to increase cable operating lengths it is wise to check voltage drop, not just for Low Voltages but for Medium to High Voltages too. In some circumstances it may be necessary to check the resistance of the cable to short circuit currents both from a thermal view point and electro-dynamically induced forces.

Load Factor FC % = (10 mi / DT) x 100 In this case the current carrying capacity as calculated using table 3, can be increased using factors given in table 7.

For other time periods, taking into account the protection characteristics of the apparatus, the value in the table must be divided by the square root of the effective time (in seconds). For different initial and final temperatures (i.e. with 90 °C and 250 °C admissible according to standards for EPR), the short circuit current (thermal limit) can be calculated using the following formula: Icc (A) = kcc x cond. cross section (mm2) √t (sec) where the coefficient kkc assumes the values in table 9.

The value is calculated by multiplying the factors K (mV/Am) of the cable then by the length of the connection L (in km). The formula to calculate the voltage drop is the following: ∆V= I x L x K (Volt) where K=1,73 x (R cos + X sen ) I = (A) effective current capacity L= (km) length of the connection R= (Ohm/km) a.c. conductor resistance at 80 °C (see table 10 above) X= (Ohm/km) cable reactance at 50 Hz (see table 10 above) Values for electrical resistance R (80°C) and for reactance X (calculated for round cables, 3 cores + 3 earth, but valid also for at cables with sufcient approximation) are also given in the above table 10. It should be noted that for conductor temperatures of 90 °C the resistance R must be multiplied by 1.03 while for a frequency of 60Hz the reactance X must be multiplied by 1.2 and the value fKor (mV/Am) recalculated.
